He may end up doing okay as a hitter, over the next 3 years... not the power you normally want from a DH, but he likely is worth more than zero. The issue is, we have at least 4 guys best suited to DH: Yoshida, Refsnyder, Casas and Devers.
Our corner IF defense sucks, and our catcher defense sucks. We can win it all without fixing those positions, but it makes it harder. To me, it is not our top priority: getting a lockdown closer is. Catcher defense is probably my number two, RHB #3 and 3B defense #4. 1B defense might be #6 behind adding another RP'er.
Getting Bregman or Arenado checks two bowes out of our top 4 needs. The cost of Bregman and Arenado are too high, and I'm not so sure their bats totally fill the need of a RHB with some power, but I think Fenway would treat bth very nicely.
If the idea is to use the money we have left to extend Crochet and or a top prospect or two and not on Bregman or Arenado, I could see the reasoning for avoiding both. Maybe there is another option, via trade, that works better. I still think we will trade Abreu as a way to "balance" the line-up.
